iOS 7 Changing UINavigationBar titleView alpha

Question

So I am using the UINavigationBar component of iOS7, but not the UINavigationController itself. When I push a new view with my custom navigation controller, I want to change

Answer 1

You can set the titleView hidden in viewWillAppear

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];

    self.navigationItem.titleView.hidden = YES;
}

You can't set the titleView alpha until viewDidAppear

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    self.navigationItem.titleView.alpha = 0.5f;
}
